[Tagging] Forest parcel with other landcover (scrub, scree…): how to map?

I think in many cases place=location would be fine.
A forest or wood ("bos" (small) or "woud" (for bigger area) in Dutch)
is typically an area with primarily trees, but also grass areas,
pools, cuttings for paths and tracks, etc.

So I was thinking that natural=wood (or landuse=forest) should only be
rendered as an boundary. It can have a name (which should be
rendered).
 For the describing the land-cover inside that area, one would use
landcover or natural=water. Those would be used to "fill the map with
colour". The landcovers areas can be multi-polygons, e.g. to cut out
water areas from landcover=tree
